Players have been struggling to access curiosity's servers since it launched.
Peter Molyneux's new studio, 22 Cans, is appealing for help to keep Curiosity: The Cube running in the face of overwhelming interest in the free mobile app.
The studio has implemented a PayPal donation button on its site so that people can contribute to the title's server and ongoing development costs.
'We are a small independent developer and due to popular demand we now offer the option for kind people to donate,'
reads a statement on 22 Cans' site. 'However big or small the donation, it will really help us make Curiosity better.'
22 Cans had underestimated how much interest there would be in Curiosity and as a result, following its launch it has been incredibly difficult to access the game at all. Those that have accessed the game have also reported issues with missing coins, the in-game currency built up by chipping away at the cube.
As of Friday, up to a million people were trying to access the server at once. Molyneux mentioned on Twitter last week that the company's server costs were going to escalate with an adjustment they had made to the app.
Speaking to Eurogamer, Molyneux stated that the studio was disappointed in itself for underestimating the popularity of its experimental game. 'We can only offer a heartfelt apology at this stage. Our programmers have been awake pretty much since Curiosity came out,'
Curiosity: The Cube invites players to chip away at a large cube in an attempt to get to the middle. Its hook is that only one person will find out what is at the cube's centre and the studio hopes that this will then be shared through social media channels. It is available as a free app on iOS and Android and although before release there was talk of microtransactions, it is currently completely free to play.
The Guildford-based studio 22 Cans has released Curiosity as its first experimental title and intends to release several more in the future. The studio will also publish the data that is collected from each experiment once it is completed.
